georges_2251 wroteUpgraded my windows from starter to ultimate (via a torrented key). It's even faster.
Thanks anyway
Was your laptop sold to you without any Windows licencing ? If it was, then upgrading to Windows 7 Ultimate will make you loose the money you've paid for, for the previous OS. By this, you can't get any Windows/Microsoft updates and be more vulnerable to security threats.
Anyway, did your GPU driver work at the end of all this ?
Also, when you buy a laptop with a problem, you should take it back to the place you got it from and not try to fix it yourself, because you might void your warranty.
